RQTARY EXPLOSIVE-ENGINE.

Appucatiion med september 2o, 191e. serial No.

To all whomc't mag/concern:

Be it known that I, WILLIAM H. Franzi, a citizen ofthe United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Rotary Explosive-Engines, of which the following is a specification, reference being had thereln to the accompanying drawings.

This invention relates to gas engines or internal combustion motors of the rotaiy type and toan arrangement thereof whereby The invention consists vin the matters here-- inafter set forth and more particularly pointed ont in theappended claims.

In' the drawings, l

Figure .1 is'a view in transverse. section, partially' broken away and partially in elevation, of`amotor that embodies features of the invention;.Fig. 2 is a view in longitudinal sectiononr aboutline II-II of Fig. 1,

example, and by end thrust. collars 9, to'rotate in concentric relation with the main chamber of the shell. A web member 10 in the chamber is secured to a flange 11 formed on or secured to the shaft 7 and carries a rim 12 that rotates in the chamber of the shell, a pair of packing rings 13 providing a close joint betweenthe rim and chamber wall on either side of an exhaust passage 14 and a compression passage 15. Both the exhaust and compression passages are segmental and eccentric tothe axis of rotationof the main shaft and are swept successively by abutments 16. The. latter are projected from radial slots inthe web 10 by means of suitably arranged spring members 17. Preferably spring perch blocks 18 journaled on studs 19 against the sides of the web 10 carry the members 17 which extend from them to engage a pair 'of abutments each, whereby the spring pressures are equalized, as only one of a pair of abutments at a time is fully pushed in lwhile moving from one passage to the other.

. A compression or explosion chamber 20 is in communication through a passage 21 with the compression space 15, a suitable valve 22, of the conical plug type, with end compression spring 23, controlling this passage.. A valve stem 24 of the plug carries a cam finger 25 that rides on a cam ring 26, suitably secured to the annular face of the rim 12. ""s indicated' inFigs. 1 and'2 the valve is in closed position as the finger is riding on the high lspot of the cam ring. An exhaust valve 27 similar to the valve 22, controls an outlet passage 28 that forms communication between the chamber 2O and theI expansion space 14.. A cam` finger-29 operates the valve 27 through the medium of the cam' ring 26. This `linger however, being ina different plane than the linger 25 of the inlet valve so that while the latter falls to the low spot of the ring over a re-`V lease shoulder 3]. of the cam ring, the linger ..29 reaches a low spot over a release shoulder 30, the latter being timed to allow the closing of the valve 27 a short time after the valve 22 is opened. An inlet nipple 33 is used to connect the sourct` of fuel supply with the compression space 15, as indicated plainly in Fig. 3, and this inlet is at a point where the abutment, as plainly seen 1n Fig. 3 has already traversed apart of the space l5 and thereby created a slight vacuum to aid in the intake of the fuel. An outlet boss 34 forms the exhaust opening of the motor from the 'passage 14, a clearance channel 35 being provided which is bridged by the abutments as they sweep around the periphery of theshell.

The combustion chambers-37 and 2() .and the explosion or expansion passa e 14 are Water jacketed as indicated at 36 y means of a suitable outer Wall.

A compression or explosion chamber V37 is connected to the passages 14 and 15 by suitable valves similar to the valves 22 and 27 of the chamber 20, but in reverse position, the inlet valve 38 being indicated in Fig. 2. A cam finger 39 that controls this valve rides on a ring 40 on the opposite annular face to the ring 26, the cam rings being set diametrically opposite so that the chambers 20 and 37 have opposite phases of operation. lVhen the valves ofthe cham-v ber 20 assume the position shown in Fig. 1, the valves of the chamber 37 assume the position indicated by the ldotted vlines in Fig. 3. V

As details of good construction, an oil drain channel 41 has a spring 42 that presses wicking 43 or the like upwardly to bear against and lubricate the periphery of the rim 12 and the rounded extremities of the abutments. abutment ends insures contact with the inner periphery of the shell and of the passages 14 and 15, while side shoes 44 projected by springs 45, aid in keeping the side joints between the abutinents and walls ineasiirably tight.

In operation, the abutments as they sweep the passage l5, gradually force the charge ahead into the chamber 20, for example, until the valve has assumed the position shown in Figs. 1, 2 and 3. Explosion then takes place at the moment that the high point of the cam ring has underrun and swung up the finger 28 openi the outlet valve 27 and the force of the iseharge is expended upon the abutments as they` successivelv pass through the channels 14.

ihile thc explosive force of thisgcharge is thus being exerted on the abutments for half the circumference of the rim 12, the companion abutinents are sweeping th channel 15 and forcing the intake gases into the companion chamber 37. 'I'hentlie lat-4 ter fires and as a rerult the explosion is exerted on the abutnienl's that have just charged this chamber while the companion abutments are rechargingr the chamber 20. ly proper timing of the intake and outlet valves scavenging of the compression chambers is obtained. both valves being held open sufficiently for this purpose. practiceI that the extension of the passage 15 to a point between the inlet 33 land the outlet 34 produces suflicient vacuum by the This rounded contourof thev lt isfound inA sweeping of this part by the abutments asA with defiecting plates 47, having screw threads 4S that deflect lubricant back again along the shaft 7l` together with other details of construction in accordance with good shop practice afford an oiling system that effectively prevents excessive Kwear. It is to be understood that the usual connections are made for distribution of the firing current and as an example of how readily the parts are operated, a main driving' gear 49 is showny on the Shaft 7 within' the easing, from which gear trains may be taken off to operate the timing and ysparking systems.

One feature of 'the construction is the greatV compression obtained by the successive charge increments." Another feature is the utilization of the explosive force of the gases againstthe succeeding abutments after the initial shock Vof discharge. A further feature is the ability to combine units to operate on the same shaft, by a proper setting of the camrrings for each in timed relationto the companion cycle.V

' Obviously, changes in the details of con struction may be made without departing 9 from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.
